Manufacturer: RCBS 31629
Full Length Sizer Dies for bottleneck cases have vents to prevent case damage caused by trapped air and for excessive lubricant. Headspace is held to minimum tolerances to avoid changing the case body length during full length sizing.
Each RCBS Die is properly hardened and hand polished. This special RCBS finishing produces a die that will withstand years and years of the abrasive type of wear caused by case sizing.
